Does the dumbbell that European and American bodybuilders usually practice weigh 100kg?
This question you asked is so funny. Dumbbell 100KG, which is 200 kg. It's good for anyone to lift a barbell weighing more than 200 kilograms. Anyone who can lift 300 kilograms of barbells can be a coach. The limit of our fitness instructor is 320, so it is impossible for anyone to lift a single dumbbell of 100KG, that is, the world weightlifting champion can lift a barbell of more than 400 kg. Those are also two hands.
